All live Joy Division performances in the film are performed by the actors themselves - there
is no stock footage. This wasn't the original plan but the band gelled together so well it was an obvious way to
go. All soundtrack music by Bowie, Sex Pistols, Roxy Music etc is from original recordings, see
below.

New Order provided the soundtrack score (i.e. the incidental music) and there is one cover version - the Killers
performing Shadowplay, over the end credits.
